Patient: 53-year-old male, two months after total left pneumonectomy for lung adenocarcinoma, multiple metastases in the left lung were found in the first month after surgery, the largest being 1.2*1.1, with metastases in the left subclavian and left axillary lymph nodes. Due to poor physical condition, poor appetite and poor activity tolerance (height 172cm, weight 45Kg, HB10g, wbc 11,000), chemotherapy was not given and ERSA treatment was chosen. The patient’s general condition is slightly better, his appetite has increased, his weight has increased by 2 kg, his mental status has improved, and his HB9g has improved. If not, what should be the next treatment? If chemotherapy is chosen, is there any benefit to the patient’s survival and quality of life? What is the approximate survival time if treatment is abandoned? Doctor: If your father’s liver lesions have increased in size or size, it means that ERSA treatment is not effective. The next step of treatment depends on your father’s general condition and the function of important organs. If the general condition is good (walking freely), chemotherapy can be considered; if the general condition is poor or if the function of important organs is incomplete, general chemotherapy cannot be tolerated and the efficacy will not be good.
